October 1. The scarcity of the species is hard to account for, as 
there were plenty of hollows for nesting sites, and no evident 
scarcity of food. 
153. (728) Sitta canadensis. RED-BREASTED NutTHatcH.—This 
species was found on the island on August 18. It may have 
bred there, as several were seen on that date and the species 
breeds on the mainland in this latitude. It became common on 
August 26 and continued so until September 7, when it became 
abundant. Most of them passed on within a day or so after the 
latter date, leaving only a few on the island. Two more were 
seen on October 11, the last day of our stay. At Ann Arbor, 
this species has been seen as early as September 10 (1908). 
154. (735) Penthestes atricapillus atricapillus. CHICKADEE.— 
The chickadee was found on our arrival at the island, on August 
16, and a few no doubt bred there. Small flocks were seen almost 
daily until October 8. The birds were found in low willows along 
the beach, as well as in the pines of the interior, often in com- 
pany with the red-breasted nuthatch and flocks of warblers. 
155. (748) Regulus satrapa  satrapa. {OLDEN-CROWNED IXING- 
LET.—This kinglet was first seen on September 20, but it did not 
become common until September 26, when it came to the island 
in some numbers with the next species. It was found all over 
the island, but seemed to prefer the tops of the pines as a feed- 
ing place. The numbers appeared to increase until September 29, 
on which date hundreds were observed. On September 350, only 
a few birds were seen, but it was still on the island when we 
left it, October 11. At Ann Arbor, it has been seen as early as 
September 23 (1906). 
156. (749) Regulus calendula calendula. RuBY-CROWNED IKXING- 
LET.—The ruby-crowned kinglet was first noted on September 19. 
It became common on ‘September 26, when it was observed in large 
numbers all over the island, with flocks of the golden-crowned. 
This species also fed mostly in the pine trees. Most of the birds 
disappeared on September 29, but a few were seen as late as Oc- 
tober 11. 
157. (756) Hylocichla fuscescens fuscescens. VrERy.—Three rec- 
ords of this species were secured, September 3, 5 and 7. It no 
doubt came with the migration of thrushes, mostly olive-backed. 
It has been found nesting at Ann Arbor by the writer (May 24, 
1904), but as a rule it breeds farther north. 
158. (157) Hylocichla alicie alicie. GRAY-CHEEKED THRUSH.— 
This thrush was first noted on September 14, and the next day 
numbers were seen all over the interior of the island. On Sep-
